Mammalian Parasitic Vaccine: A Consolidated Exposition

Deepak Sumbria* and LD Singla

Parasites are highly prevalent in livestock worldwide and infect over one fourth of the human population also. Parasites are successful in evading host immune responses, and vaccination can prove to be an effective way to control them. However, currently very few vaccines are available against parasitic infection. Two important limitations in the emergence of effective parasitic vaccines are incomplete understanding of the immunoregulatory pathways involved in immunity, and the lack of precise information regarding host-pathogen interactions. Precise identification of parasite genes and the role of their products in parasite biology may assist in the identification of useful antigens, which could then be produced in recombinant systems. Many recombinant parasitic antigens have been successfully used in livestock and new vaccines are under trail. Numerous vaccine antigens are defined to target a wide range of parasite species. Thus vaccines offer a green solution to control disease. Vaccines have multiple beneficial effects such as improvement of animal health and welfare by controlling animal infestations and infections; diminishing resistance to anthelmintics, acaricides and antibiotics; improving public health status by controlling food borne pathogens and zoonoses aspect related to animals; keeping animals and the environment free of chemical residues and maintaining biodiversity. This current review is an attempt to consolidate all commercial or under-trail vaccine for mammalian parasites.
